The bucket has a hinged base with two slots fitted with cutting teeth. The base is locked, the bucket is lowered down the hole and filled by a rotary action. When full, the bucket is brought to the surface and pulled away approximately 5 metres from the drill hole by a boom and pulley system.

Surface miners operate in a similar way to road milling machines working on asphalt or concrete. A special cutting drum cuts and crushes the material. Robust loading conveyor systems then load the material onto trucks or dumpers or deposit it in windrows behind the machine.

Mine managers and individual miners need to adhere strictly to operational safety procedures. Employers need to provide the right tools and training to every employee to protect the life, health and safety of the workforce, as well as to protect valuable worksites and assets.
